We got this event when trying to install the latest Java runtime engine on a Windows Server 2003 running Terminal Services while connected remotely through RDP.

Even though we were logged in as an Administrator, we got the popup "Only administrators have permission to add, remove, or configure server software during a Terminal services remote session. If you want to install or configure software on the server, contact your network administrator."

You should then be able to install the package. Apparently, some MSI packages suffer from this problem and need this registry value to be present and set to 1.
